1 Comment on KTR being worked on

“I don’t know about this. It (the FreeBSD code) looks poorly designed to me.

Also, the FreeBSD code probably used mutexes where you are using a token. For ktr_tracepoint() to be callable from ‘anywhere’ you can’t use a token there but must instead convert the code to use a critical section and per-cpu arrays.

Also, 1024 entries is probably not nearly enough for a tracepoint utility to be useful. We’d need a lot of entries… a million or more, for it to be really useful, which implies dynamically allocating the array at boot time rather then declaring it static.”
